Students, on the other hand, can write their own class or lecture notes in iTunes U.

There’s also a Materials tab where you can see all the materials needed for a course collected in one spots. They can contain audio, video, books, documents (PDFs, Pages, Keynote), and even Apps. And if you don’t have any materials, you can easily buy them with iTunes U.

Professors can even download or stream their lectures for remote students.

According to Phillip Schiller, Senior Vice President of Worldwide Product Marketing at Apple, at least six universities are already using iTunes U: UCLA, Berkeley, University of Paris, Tokyo, and the Harrisburg Area Community College. Between them, they’ve already created over 100 new online courses. Pilot programs are also underway at MIT, Duke, Yale and Stanford.

But even though iTunes U focuses on higher education, K-12 can now sign up too.
